【摘要】：桥式起重机（简称行车），广泛用于工厂、车间、仓库等处的物品装卸。行车在钢铁生产过程中起着重要的作用，参与特定的工艺操作，通过指令吊运铁水、钢水、废钢、板坯和各种成品，并跟踪记录吊运物品的位置。行车工作环境特点是使用频繁、条件恶劣，工作级别较高。随着钢铁行业的高速发展，产量不断上升，对于行车通信高效稳定的要求也越来越高。宝钢某区域称重行车自1998年投运以来，通信系统存在较高的故障率，且故障恢复时间长、设备老化、稳定性差等因素，，严重影响了正常的作业。针对高故障率现象，有必要设计先进的行车通信系统，满足日常生产需要。本文以宝钢某区域称重行车为对象，对行车无线通信控制系统进行了研究，并建立系统软硬件平台。 1.比较多种无线通信技术特点，针对行车自身特点和现场运行环境，确定了数据转换方式和无线通信方式，制定了控制系统的整体方案。 2.研究了单片机技术，从系统元件、硬件电路、软件结构和软件程序等方面考虑，运用抗干扰技术，设计了地面站子系统，完成子系统电路设计、软件编程和硬件设计。 3.运用了无线网络技术，设计了无线通信子系统，建立行车与主机之间快速、可靠地通讯连接，实现对行车的群调度作业。 4.运用笔者所在公司自主研发的信息交换中间件（XCOM），设计了车上站子系统，完成监控终端的功能和界面设计。
[Abstract]:Bridge crane (short for driving), widely used in factories, workshops, warehouses and other goods loading and unloading. Crane plays an important role in the process of iron and steel production, participates in specific process operation, hoists molten iron, molten steel, scrap steel, slab and all kinds of finished products, and keeps track of the location of lifting goods. Driving working environment is characterized by frequent use, poor conditions, high working level. With the rapid development of iron and steel industry, the output is increasing, and the requirement of high efficiency and stability for traffic communication is becoming higher and higher. Since the operation of a weighing train in a certain area of Baosteel in 1998, the communication system has a high failure rate, and the failure recovery time is long, the equipment is aging, and the stability is poor, which seriously affects the normal operation. In view of the high failure rate, it is necessary to design advanced train communication system to meet the daily production needs. In this paper, the control system of wireless communication in a certain area of Baosteel is studied, and the software and hardware platform of the system is established. Compared with the characteristics of many wireless communication technologies, the data conversion mode and the wireless communication mode are determined according to the characteristics of the vehicle and the field operation environment, and the overall scheme of the control system is established. 2. The technology of single chip microcomputer is studied. Considering the system components, hardware circuit, software structure and software program, the earth station subsystem is designed by using anti-interference technology, and the circuit design of the subsystem is completed. Software programming and hardware design. 3. The wireless communication subsystem is designed by using the wireless network technology, and the fast and reliable communication connection between the train and the main engine is established, and the group dispatching operation of the train is realized. 4. Using the information exchange middleware (XCOM), developed by my company, the subsystem of the vehicle station is designed to complete the function and interface design of the monitoring terminal.
